Abstract

The present invention obviates the problems inherent in the prior art synthetic resin pallets and aims at obtaining a synthetic resin pallet constructed to protect reinforcing ribs peripheral to a port area of a fork entry port from being broken by an impact and to protect an edge of a block adjacent to the port area of the fork entry port from being broken by the impact, and therefore exhibiting a high durability. A synthetic resin P of the present invention comprises a top board 11a, a bottom board 11b disposed opposite to the top board 11a, a plurality of cylindrical blocks 12 for connecting the two boards, and a fork entry port 14 formed between these blocks 12. This synthetic resin pallet is manufactured by making, face to each other, one pallet constructive member 10a including one board 11a of this pallet and cylindrical block constructive members 12a, 12b integrally formed on the inside of the board 11a, and another pallet constructive member 10b including another board 11b of the pallet and block constructive members 12b integrally formed on the inside of the board 11b, and by integrally welding the block constructive members 12a, 12b to each other. Reinforcing ribs 13 are formed lengthwise and crosswise on the inside of the board 11a or 11b of at least one pallet constructive member 10a or 10b, and the reinforcing ribs are constructed of hollowed surface reinforcing ribs 13b formed lengthwise and crosswise on the inside of the surface of the synthetic resin pallet.
